public int getEPSGCode()
```
    Returns the ESPG code for this projection, or 0 if unknown.
  - setUnits
```
public void setUnits(Unit unit)
```
  - getUnits
```
public Unit getUnits()
```
  - getHeightOfOrbit
```
public double getHeightOfOrbit()
```
    Get height of orbit - Geostationary satellite projection
    
    Returns:
    
    Height of orbit
  - setHeightOfOrbit
```
public void setHeightOfOrbit(double h)
```
    Set height of orbit - Geostationary satellite projection
    
    Parameters:
    
    h - Height of orbit
  - initialize
```
public void initialize()
```
    Initialize the projection. This should be called after setting parameters and before using the projection. This is for performance reasons as initialization may be expensive.
  - normalizeLongitude
```
public static float normalizeLongitude(float angle)
```
  - normalizeLongitudeRadians
```
public static double normalizeLongitudeRadians(double angle)
```
  - setGamma
```
public void setGamma(double gamma)
```
  - setGammaDegrees
```
public void setGammaDegrees(double gamma)
```
  - setNoUoff
```
public void setNoUoff(boolean no_uoff)
```
  - isGeographic
```
public java.lang.Boolean isGeographic()
```
    Is this "projection" longlat? Overridden in LongLatProjection.
  - equals
```
public boolean equals(java.lang.Object that)
```
    Represents quality between possible outputs of project(ProjCoordinate, ProjCoordinate). Subclasses of Projection should capture additional state that is used in the project method and delgate to base. Note: The name of the projection is not part of equality.
    
    Overrides:
    
    equals in class java.lang.Object
  - hashCode
```
public int hashCode()
```
    Hash of those fields considered in Projection equalituy. Subclasses that override equality should override hashCode.
    
    Overrides:
    
    hashCode in class java.lang.Object
